Hello and welcome,
Searching on Google Maps comes up with one place called Anjo Station, at 34.959945,137.087168. It does have a Wayspot, but there are 3 other Wayspots in the same L17 S2 cell. Only 1 Wayspot is allowed per L17 S2 cell in PoGo, so it may be one of the other 3 that is a stop/gym in PoGo. If you are subittings the station, it most likely is being marked as a duplicate.
While the Ingress map no longer syncs with Wayfarer, this is how the cell looks as of May 23rd, 2025. The station is in the north of the cell, and there are 3 other Wayspots to the south of the station.
If you would like more info on S2 cells and PoGo, please see this post:
